Etymology: Nothobranchius: Greek, nothos = false + Greek, brangchia = gill (Ref. 45335); kadleci: Named for the late Jaroslav Kadlec (1951-2006) from Brno, Czech Republic, a renowned killifish breeder recognized worldwide for his articles on killifish breeding, ecology, and his photographs. To be pronounced 'khadlatsi'.

Morphology | Morphometrics
Nothobranchius kadleci is distinguished from N. furzeri by the smaller depth of the dorsal fin (17.9–31.0 % SL vs. 27.4–37.7 % SL in N. furzeri in males, 14.9–17.6 % SL vs. 19.0–21.9 % SL in females) and smaller depth of the anal fin (17.4–25.8 % SL vs. 22.4–32.4 % SL in N. furzeri in males, 17.3–19.2 % SL
vs. 19.3–24.5 % SL in females), larger preanal distance (64.0–65.8 % SL vs. 58.9–61.3 % SL in N. furzeri) in females and presence of red colour on gill membrane and lips and red pectoral fins (N. furzeri does not possess red colour on gill membrane and lips and typically have yellow pectoral fins), absence of black
marginal band on caudal fin (present in some male N. furzeri), and a higher amount of red on caudal and dorsal fins and on body in males.
It is distinguished from sympatric N. orthonotus (including putative N. kuhntae and N. mayeri) by the
shape of the frontal region (convex in N. kadleci, flat in N. orthonotus), the presence of red pectoral fins with white margins, often with a bluish tint (N. orthonotus possess transparent or whitish pectoral fins with red margins), red background colour on the head covered with small to large light blue marking (N. orthonotus possess red spots on white to grey background colour of the head and, in most populations, also on anterior ventral part of the body), shorter preanal distance (range 58.4–61.2 % SL vs. 62.7–72.5 % SL in N.
orthonotus), and distance between pelvic and anal fins (10.2–13.5 % SL vs. 13.4–16.6 % SL) in males.
Nothobranchius kadleci differs from sympatric N. rachovii in males by a lack of black margin of the caudal fin, distance between pectoral and pelvic fins (15.1–21.7 % SL vs. 12.8–16.7 % SL in N. rachovii),
minimal body depth (15.0–16.9 % SL vs. 13.5–15.4 % SL) and eye diameter (22.1–27.3 % HL vs. 26.0–32.6 % HL) and in females by preanal distance (64.0–65.8 % SL vs. 61.8–64.5 % SL), length of caudal peduncle (20.1–21.6 % SL vs. 13.4–20.1 % SL), depth of dorsal fin (14.9–17.6 % SL vs. 16.8–23.2 % SL), and depth of anal fin (17.3–19.2 % SL vs. 21.0–23.2 % SL) (Ref. 83370).
Africa: central Mozambique (Ref. 83370). The latitudinal extent of the range of N. kadleci is over 300 km primarily along the north-south axis (Ref. 83370).
Collections made from an altitude ranging from 24 to 82 m above sea level; maximum water depth of 10-70 cm in 2008 and 50-100 cm in 2009; very turbid water and soft muddy bottom; littoral vegetation present in 50% of the pools, with some Nymphaea sp. vegetation in 2 pools; conductivity between 68-300 µS.cm-2; water temperature during collection 27.7-38.2 °C; associated fish species included Nothobranchius orthonotus (10 cases), N. rachovii (2 cases), an unidentified small Barbus sp. (2 cases), Tilapia sp. (1 case), Protopterus sp. (1 case) and Clarias gariepinus (1 case) (Ref. 83370).
